Sergeyev House on Lenin Prospekt, 14 in Vyborg

Sergeyev House sits on Lenin Prospekt at number 14 with its unusual three-sided shape and facades made of natural stone accented by Gothic gables. The Rococo Revival style design creates sharp corner points and steep rooflines that give the building its distinctive appearance.

Swedish architect Fredrik August Odenwall designed this building in 1883 for a major trading company operating in Vyborg. It was built during a period when Finland was under Russian control and Vyborg served as an important commercial hub in the region.

This building reflects the architectural preferences of 19th-century Vyborg's merchant class, who favored decorative stone facades and distinctive shapes to display their status. Walking past it today, you can sense how such houses once anchored the city's commercial neighborhoods.

The building sits on Lenin Prospekt, a main street in Vyborg that is easy to walk and explore on foot. Its distinctive triangular shape with sharp corners makes it visible and easy to spot from different angles as you move through the area.

Local people and visitors call this the 'Witch's House' because of its strange triangular shape with two very sharp corner points. This nickname has stuck for generations and shows how the building's odd form captured people's imaginations.
